Gener al Review on Effects of Soil and Water Conservation Measur es on Water Resour ces in China
|
Abstract:
In recent years,with more and more officials and professionals paying attention to the problems such as soil erosion and water loss,the exquisite contradiction between water supply and demand,whether soil and water conservation measures on upper regions would have effect on the amount of water resources of the lower reaches is a scientific issue to be discussed and probed into urgently.Primary achievements of effects of individual soil and water conservation measures on water resources as well as benefits of runoff reduction of watershed management in China have been reviewed and analyzed synthetically on the runoff plots scale and whole watershed scale respectively,and the benefits of runoff reduction of some large watershed have been analyzed and compared with each other.Some existing problems in this research field at present have been expounded and prospect is put forward at last.
